Communication system
First Claim
1. A communication system comprising:
- a first communication device including a first antenna, the first antenna outputting a high frequency alternating current power;
a second communication device including a second antenna and a power receiving circuit, the power receiving circuit receiving, via the second antenna, the high frequency alternating current power output from the first antenna;
a power line connected between the second antenna and the power receiving circuit, wherein the power line includes a first power line, which is positioned between a predetermined portion of the power line and the second antenna, and a second power line, which is positioned between the predetermined portion of the power line and the power receiving circuit, the first power line includes at least one first semicircle portion having a semicircle shape and the second power line includes at least one second semicircle portion having a semicircle shape, the at least one first semicircle portion and the at least one second semicircle portion being combined together to provide at least one loop-shaped antenna; and
a third communication device including a third antenna, the third communication device receiving, via the third antenna, the high frequency alternating current power output from the at least one loop-shaped antenna, whereinat least two of the first communication device, the second communication device, or the third communication device transmit or receive communication signals via corresponding antennas, andthe first power line and the second power line are twisted with each other to configure a twisted line pair at a portion other than the at least one loop-shaped antenna in the power line.

Abstract
The communication system includes a first communication device, a second communication device, and a third communication device. The first communication device outputs a high frequency alternating current power, and a power receiving circuit of the second communication device receives the high frequency alternating current power via a second antenna. A power line is connected between the second antenna and the power receiving circuit. A first power line has a first semicircle portion and a second power line has a second semicircle portion. The first and second semicircle portions are combined together to provide a loop-shaped antenna. The third communication device receives the high frequency alternating current power output from the loop-shaped antenna. At least two of the first, second, or third communication devices transmit or receive communication signals using respective antennas. The first and second power lines are twisted with each other at a portion other than the loop-shaped antenna.
